If you put the seeds in a wet paper towel and then put that in a plastic ziplock bag, they will start to grow tiny roots, then its time for dirt. You can also peel off the seed covering, which I did, to help the process go a bit faster.
I put the seeds into a paper towel on the 2nd of this month, the 18th I put each one into their own small cup of dirt. The very next day 2 of the orange seeds sprouted! Yes, I said sprouted! I couldn't believe it myself, in fact I didn't even think I was looking at little sprout but a closer look revealed the truth, the seedlings had come up!
Only time will tell if these little guys will continue to grow and even more importantly, make it through the tough cold winter months ahead. I would love to have a bunch of little seedlings to take outside for the spring time sun and warmth.
Growing these seeds so far has been really fun! Orange trees, lemon trees, and lime trees make great house plants and I suggest you try growing them yourself, but that's just my two cents.
